rHo'roGRArHrc-PEINTING DEVICE.

` Application inea December s, 1920. serial Noizaeio.`

To all 'whom itmay concern,.- v Be it vknown that I, CHARLES at Minneapolis, inthe county of Hennepin and State of Minnesota, have invented certainnew and useful Improvements in Photographic-Printing Devices; and I do hereby f declare the following to` be a full, clear, and

enlarged or'reduced sizes; and to such ends,

generally stated, the invention consists Vof the novel devices' and combinations .of devices hereinatterdescribed and defined in the claims.

The device comprisesv a suitable upright support usually and. herein designated as an easel, and "a printing frame that `is detachably and pivotally .connectcdthereto The detachable teaturemakes it possible to interchangeably use a plurality 'of frames, y.of the saine or of difterentcharacter, in'connection'with thefcommon easel, and the pivotal connection permits a frame to be turned and setwith its longest dimensions either vertical or horizontal. Also, the pivotal connection permitsthe frame to be set more or less oblique to a vertical or horizontal position so as to bring the sensitized printing paper into -parallelism'in respect to the negative, when the negative is not set in a true vertical :or true horizontal position, as the case may be.. The invention also involves certain other novel features, as will hereinafter appear.

In the accompanying drawings, which illustratethe invention, like characters indi- Of. Fia 1;;

cate likel parts throughout the severalviews.

Referringto the drawings: Y.

gFig. 1 is a frontfelevation showing the improvedprinting device;

' ,Fig.'2 is a plan view thereof;l

Fig. 3 is a verticallsecton on the 11,1716 3 3 p BQ, STRUBI/im. n ama citizen of the United v`States, residing Fig.4 is afront elevation showing a somewhat modified' form ot printing trame;

Fig. 5 is a top view thereoi; and Fig, 6 is av section on the line 6--6V of Fig, I The easel, as shown and preferably constructed, comprises upright. bars 7 supported by feet 8 and rigidly connected by transverse y.tie bars 9 and 1,0. The upper and lower tie bars 9 are flush withthe upright bars 7, while the intermediate tie bar 10 is securedon the rear edges of said bar 7.

Connected to the lower tie bar` 9, by hinges 11, is an arm 12 that extends upward past the intermediate bar 10 and, at the front face of its free end, has iafrigidly secured socket plate 13 formed with an approximatelyv V-shaped notch 14e, back of which said arm 12 isrecessed or cut away at 15. The numeral 1,6 indicatesa clamping bolt that is passed throughthe uprightend ofthe arm 12 and through the tie bar. 10 and is fprovided, at its rear end, with a thumb nut 17, the head ot-said bolt "being within the recess 15. A. learp spring 18 is anchoredv at its lower rend to the arm 12 and, atits free end, bears against the tie har 19 and yieldingly ypresses the arm 12 forward.

` The printing trame shown in Figs. 1., z and 3 is indicated as an entirety'by the numeral 19 and it vis provided on its longitudinal edges with retaining ribs or strips 20, the inner edges of whichare spaced from the back plate ot said trame so that they will overlap and retain,V the longitudinal edges of a Vsensitized sheet. ofprinting paper y. A thirdv margin strip 21 is secured to the vlower ends vofthe strips 20 and thus spaced outward slightly Ifrom the back plate ot the trame. Pivoted at 22, to the inner side ofthe strip21, is an adjustable stop which also serves an additional function presently to be described.y i

Ajfourth margin strip 211 ispivotedv toA the.

upper end ofone of the strips 20. and, at its free end, works inthe guide yokel 25 applied to the upper end of the otherstrip 20. This strip 24 is spaced 'from Vthe back` plate of the frame far enough to permit the sensitized CilA- sheet y and also a mask, il' desired, to be inserted under the same and under the edges of the strips 2O and under the strip 21 so that the photographic print will be given a white marginal edge, even when the mask is not used. A light coiled spring 2G, attached to the 'free end of the strip 2tgand to. the-upf per portion or one'oi'fthe strips 20, normar- 1y yieldingly holds the free end of. said strip 211 against onefextremi-tyy-Of:the-yoke- 25. As shown, the back plate ol' the frame 19 is cut away at 27 and thc. central vportion of the pivoted strip 24 is cut away at 28 so as to facilitate position-ingand removal off the sheet The central'cross bar '19ottheprinting frame 19, at its center, is provided; with a headed stud 29 shown asatllorded by a screw. Thisl headed stnd is adapted to be inserted into the socket afforded by the forked plate landits notch'll, andfwhen'soengaged, will'ailord a pivotnon which the printingframeanay be -rotated fromvertical to horizontal positions or any` other' positions desired.- When said stud'is thus'engaged by-tl1e`p1atef13' andthe nut l17, yon'the bolt 1b, is'tightened, the socket "arm 12 -will be moved rearward; carrying with'itthe plat-e land causing the latter to lpull on-.the studv 29 and thereby cause the back'ofthe printing frame to be frictionallyclamped against the face or the'easel. Thus, the. frame may be clamped in any desired position.- It may be set in-a true vertical p osition'or, in a true horizontalposition4 and, as the `negative is slightly out of ytrueverticall or horizontal position, theprinting frame maybe moved corH respondingly into parallelism therewith so that the image will be printed on the sensitized paper y and properly positioned in, respectto the edgesthereof. l

VV'hen the vnut'17 is loosened, the spring 18 will move. the arm l12 `forward, .thereby releasing the printing frame from clamping contact'y with the easel and: permitting the same to be readily moved `from the notched plate 13. Hence, as is evident, a plurality of printingr frames may be interchangeably used on the easel and may be quickly applied to or removed therefrom.`

In the formi ofprinting frame shown in Figs. l, 2 and '3, the margin st-rip 24'1nay be pressed forward `when desired so .as-to-per-v mit the adjacent'edge of the;sheet;onpaper y to be engaged bya ngerandthumb for the purpose ofremovingl the'same from the frame. Moreover',1 by giving the4v pivoted stop 23 a quick inward movement against the paper sheet y, the lattermay bel projected from the iframebeyond theinargin-strip 24 'y so. that they. may be j engaged i and 'its jre-1 moval from the `frame completed."v

Y Theprinting Ylirameshowirin Figs. ,4, 5 and G-'fditfers-` inf the :frame vdescri'bedinthat the cross bar 24a, which corresponds to the jacentedgeoffsaid sheet jy.

cross bar 24; of the first described frame, is a lined bar. Also, this frame, back of the iixed side margin strips 20, is provided with parallel guide channels, one for the sensitized paper sheet y and the other for a mask or vignetting frame y1, (see Figs. 5 and 6).

Forkickingor projectingthe sheet y partly iout"I ol the printing iframe, I'provide a slideBO mounted in one side of the frame and provided;ahonefend with a thin ejecting linger 31 that is engageable with the ad At its other end, the slide 30 has a flat portion 80 providedat the topo-tithe frame 19 with a fin-- ger piece or lug 30". The numeral .32 indicates a light coiledispring anchored" toonev side` of the frame 19 andrattached atits other end-'to theslide 30 and-normallyholding Asaid slide in its inoperativeV posi-tionv shown in Fig;v 6:;with the inner end o-thle bodyA portion@ 30 engaged witlrthe transverse cross bar-10^ofgthe frame.- This crossgban 10, like.

that of-the first described frame, has a hleadl ed stud 2S)A for, engagement with the notchy 1l of the socket lplate 13.,

After the imagehasbeen printedongthe sheet i ,itl isfadapted-to nbe partly 'projected fromltheframe by-engaging atinger with the lug 30h andthereby pulling the Slide 30 upwardor against'the tensionof'the spring Asis evident, either one ofthe two typesy oflliramesor anysiinlar frames, may be ap plied; at will, to the easel in the-manner de.- scribed inconnection with the construction illustrated in Figs.` 1, 2jand This ali'ords means `orpuielrlyl and conveniently printing bythe use ofa plurality of'fraiiies--a1id'it also provides Ameans for accomplishing `all of the required]A adjustments' in doing high gradework. Moreover, theconstruction described is simple and 'or' small cost.
